Historical fire pits were sometimes built in the ground, within caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced hazardous or irritating smoke inside the dwelling.Fire pits grown into raised hearths in buildings, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where a open fire burnt with the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from spreading through an area and vent it outside via a wall or roof. These could be placed against rock walls, rather than taking up the middle of the space, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke outside. They made it possible to provide the fireplace a draft, and also made it feasible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general use immediately, however, as they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a lengthier area on top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and out of the construction. The shallow design also improved greatly the quantity of radiant heat projected into the space. Rumford's design is the basis for modern fireplaces.
Rather it depended on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality gems. Stone fireplaces at this time were a sign of prosperity, which to a degree remains the notion today.A fireplace is a structure made of brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a space. Modern fireplaces change in heat efficiency, based on the design.Historically they have been utilized for heating a home, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, where the projecting courses of brick function as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain at the chimney is a far greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which divides up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a significant health risk. The EPA writes"Smoke may smell great, but it is not great for you.Types of fireplacesArtificial fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
In the United States, some states and local businesses have laws limiting these kinds of fireplaces. Additionally, there are air quality control issues because of the amount of moisture they release in the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the place that's heated, and port all exhaust gasses into the outside of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were fire pits compared to modern fireplaces. They have been used for heat on cold days and nights, as well as for cooking. They also functioned as a gathering place inside the house. These fire pits were generally based within a space, allowing more people to collect around it.

Many defects were found in early fireplace designs. Along with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace designers of this time were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It had been smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, as opposed to their size.
From the 1800s newest fireplaces were made up of two parts, the surround and the insert. The surround comprised of the mantlepiece and sides affirms, usually in wood, granite or marble. The insert was fire burned, and was built of cast iron often backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian era were thought to add a cozy ambiance into houses.Bold Flame Vanderbilt 68 in.

Some fireplace units include a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency can also be increased by means of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be made from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the atmosphere. The best way to estimate the output of a fireplace is if you notice you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a massive fire window, allowing an efficient heating process in two stages. During the first stage the first heat is provided through a large glass while the fire is burning. During this time the structure, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for several hours during the second phase. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Based on temperatures 1 to two daily firings are enough to ensure a constant room temperature.fireplace media console
